My invention relates to railway rolling stock and consists in a novel locomotive tender construction and more particularly in a tender underframe adapted. to form all, or a substantial part, of the bottom of the tender tank and adapted to mount stoker mechanism.

One of the objects of my invention-is to provide an underframe, having the characteristics referred to, which is as wide asthe tank structure and is provided with sills at its sides located high enough above the rail *topermit access under the side sills and adj acent'bottom portion of the-under-frame and over the trucklwheel pieces below the underframe.

Another object of my invention is to provide a bolster and center sill-construction for such an 'underframe which will form water compartmentsa Another object of my invention is toc onstruct an underframe having side sills and adjacent structure as described and will also have an intermediate structure adapted to mount'stoker mechanism at a lower level than v the top of the side sills, Another object of my invention is to provide for manual access through an underframe forming'a water compartment whereby operators can getat stoker mechanism front beneath the underframe.

These and other detailed objectsof my invention are attained by the structure illustrated in the which 7.

Figure l is a top view of a -locomotive tender underframe, an intermediate part of the same being broken away to facilitate the.

illustration.

-Figure 2 is a longitudinal vertical section taken approximately on the center line of the underframe. 5

. Figures 3 and 5 are end views of the right hand and left end of the underlirame as shown I section lines of Figure 1. r

in Figures 1 and 2.

Figures 4, 6, 7, 8, 9 and 10 are vertical trans; verse sections taken on the corresponding The underframe preferably comprises? one piece casting, although it may be made of two or more units riveted toeach other or accompanying drawings in -r.ooomo'r vn-'rnnnnn STRUCTURE ing portion of the underframe, b'emade as a 5 single unit, irrespective of 'the restof the underframc. C J r I The main membersof the underf'rame are the side sills 1,-the end sills 2, bolsters 3, the box-shaped center sill 4 and intermediate 0 sills 5; These sills are connected by a substantially continuous lower web member 6' which also forms the bottom of the center sill and the bolsters:

Horizontal flanges 7, 8, suitable reinforcement for the upper portion of thetender. frame'and some of these flanges,

such as be'stfshown in Figures 1,4 and 7, ex-

tend across thebolster and center silland' connect the upper portions of the right hand bolster and center sill and adjacent intermediate sill 5 and form the bottom of a eompartment 12 adapted to receive stoker mechanism which I have indicated generally at S. In

order to provide for. they location of the 7 stoker mechanism on the tender in alignment with or at the same height as the stoker mechanism on the engine, the portions of these flanges which form the bottom of the stoker compartment are depressed below the level of 8a the top of the'bolster and center sill and side, sill top flanges in order to accommodate the stoker mechanism at a lower level than would be possible if the top faceofthe underframe was in the same plane from side sill to side sill and from end to end. A portion of the bottom of the stoker compartment is provided with a pad 13 on which a wear plate 14 ismounted to provide a track for the stoke r mechanism S and this plate maybe renewed, when desired. a i

The tender side sheets are riveted or Welded to the sidesills as shown in Figure 7 and together with'the sills form side girders for carrying the loads at the side of the tank;

and as agresult of this construction the depth and weight of-the side sills are much less than would be necessary for an open type tender frame for a tank having 9 1O and'll form 65 the same capacity. Other advantages of thetshallow side sills for my underframe structure arethat the bottom of each side sill is a substantial distance above the level of the bottom of the center si'll and above the truck frameor wheel piece T, the top of side sills are the same height or level as the highest portions of the center sills and bolsters, and web 6 extends'inwardly of the underframe from the bottom of side sill 1 for a substantial distance to provide access to the truck parts by means of the space between the web and truck frame wheel-piece. Within the truck. side frame, member 6 extends downwardly and inwardlyv to the .bottom of the center sill. This arrangement of web, sills and bolsters provides a construction that is much simpler than one' where the top of sills and bolsterswould belowered to the level of the 'bottom of the stoker compartment, as the web 6 which extends inwardly from the bottom of the side .sills would have to be made with large recesses on the underside to provide foraccess 4 between the same and the truck side frame.

The stoker-recess iswider at the front end than at the inner end as shown at 31, so as to accommodate the drive shaft 32 when the The side of stoker apparatus swings laterally relative to the underframe while the locomotive is on a curve.

formed, in part, by the offset 15 in flange 10 and, in part, by a suitable plate 16 mounted on the flange 10 by welding direct'or by means of a connecting angle 17 which may be riveted or welded to the plate and flange. The top of the stoker compartment and bottom and side of coal compartment is formed by a horizontal plate 18 which extends laterally and upwardly (not shown) to the tank side plate 19 riveted or welded, or otherwise'secnred, to

the side sill 1. y

All of the space below top plate 18, and to the outside of upright plate 16', forms a water com rtment extending along the side of the sto er compartment and this water compart- -m nt is extended downwardly and inwardly through the underframe throughout the length of the bolster and throughout the length of the center sill. At the bolster, the lower web 6 of the underframe is provided with pads 20 for mounting suitable side bearings. At the sides of the bolster, the lower web 6 may incline more directly from the side sill to the center sill as best shown in Figure 8. This construction provides for the drainage of the water in the tank to the center of the underframe whereby substantially all of the water may be drawn off, if necessary.

It is desirable to get'atthe stoker mecha nism without draining the water from the tank and without necessarily removing all of. the

I vide such accessibility y forming coal from the fuel com artment and 1pmsuitable openings 21 and 22 by means of u rlght webs 23 and 24 extending transverse y betweenithe stoker compartment is the centersill and the adj acentiintermediate sill 5. These openings also permit. the'pas- 4 .sage of dirt from the bottom of the stoker compartment through the underframe.

In order to facilitate the molding'of a cast tender frame, such as I illustrate, I provide the various webs with suitable openings 28' and, after the casting is completed, core sand may be removed through these openings and the openings thereafter closed bymeans of plates 29 preferably welded over the same.

' Additional features of the preferred structure are the integral step 25 and integral safety chain 'lug'26 andsuitable members 27 forming a draft pocket. At 30, I illustrate a center plate structure which is adapted to facilitate lubrication of the truck and body center plate elements but this lubrication features does not form any part of my present invention.
